To all whom it may concern:

Be it known that I, ERNEST PUGI'BET, a citizen of the Republic of France, residing in the city of Mexico, Federal District, Republic of Mexico, have invented certain new and useful Improvements in Cigarette Machinery, of whichthe following is a specification. I

This invention. provides an improved mechanism for extracting from cigarette machines and from the tobacco which passes therethrough the fine dust or tobacco powder which is produced in the operations of the machinery upon the tobacco. An embodiment of the invention is illustrated in longitudinal cross-section in the accompanying drawing.

The drawing shows a machine of large production for distributing or combing or spreading the tobacco, with the improve-- ments of this invention applied thereto. A

The tobacco is laced in the vessel A, whence it is carried by the combing devices indicated on to a leather belt B which feeds it to the brush C which rotates very rapidly and carries the tobacco in the desired condition into the feeder D. There is a. considerable quantity of dust formed always in the distributing or spreading chamber E upon and above the belt B and again in the chamber or feeder D. This dust if carried forward with the tobacco goes partly into the cigarettes and partly 1nto the ,atmos-.

phere surrounding the machine. In either case it has only a harmful effect. So much of it as goes into the cigarette is largely inhaled by the smoker, its fineness permitting it to be drawn into themouth and throat, where it is both unpleasant and injurious to health. .The powder which escapes into the atmosphere about the machine is breathed b the employees in the It is a serious matter, the quantity of powder amounting to ten or twelve pounds per day per machine, and being so fine as to noticeably befog the air in the factory. -By my presentinvention I have succeeded in extracting all or nearly all of the fine dust so as .to produce a clear atmosphere in the factory and to produce cigarettes having little or no dust in them.- At the same time the dust extracted can be utilized as a by-prod not, either as a fertilizeror-as an insect exterminator for plants or as a source of nico- -width of the top of the chamber Patented Oct. 25, 191 0.

tin for medicines and insecticides. Even if the dustwere thrown away itsextraction is which the dust is formed and inclosed, and

at 'the points where the dust can be most effectively drawn out. For example, the

points E and D at which the dust accumu- V lates are inclosed so as to prevent the escape of dust into the surrounding atmos-.

phere, and an inlet pipe to the suction apparatus is connected to each of the chambers E and D thus formed. A suction fan F driven'by any suitable motor has an inlet main G provided with branches'leading to the desired points of the machinel 'two branches H and J- are connectedto the These mouth-pieces K and L respectively leading from the chambers of the machine by means of sleeves of rubber or other flexible tubing M and N. The branch H is connected to the upper part of the chamber E, at which noint the dust tends to'accumulate. At the entrance to the mouth-piece K is arranged a collecting box or trough, O, which is simply a. tin or other sheet-metal box connected to the mouth-piece K and extendin the full li and having its lower openin not more than four or five centimeters wi e. The mouth-piece L is provided also with a collecting box P placed in the upper part of the feeder D and embracing the full width thereof. In order that only the dust and not the regular particles of tobacco produced in the feeder D shall be sucked out, the suction mouth is formed in the upper partof the feeder D. The collecting box P is likewise extended the full width of the feeder, and is provided with a narrow mouth leading into it from the feeder. tected from the larger particles of tobacco This narrow mouth Q, is pro loo by a shield R which overlies it. The feeder is closed atthe top substantially hermetically by means of a board S running across i the top. A

The discharge tube T from the fan F.

empties into a receiving box U provided with diaphragms V extending alternately from the-top and from the bottom nearly to the-opposite side of the box, so as to compel the dust-to pass downward and upward and close to the surface of the Water V which is carried in the box; any desired number of diaphragms being used so as to bring the dust into contact with the water often enough to cause the latter to absorb substantially all the dust. Thus the air escaping at the outlet X is substantially free from dust, and the latter is collected in the water and removed as occasion requires.

Vhat I claim is:

1. A machine of the class described including in combination a machine having a chamber E, means for sucking the dust out of said chamber through a mouth at the upper part thereof, and a collecting box 0 adjacent to such mouth.

2. A machine of the class described including in combination a machine having a feeder l in which dust is formed, means for sucking the dust out of'said feeder through a mouth at the upper part thereof, and acollecting box P adjacent to such mouth.-

In a machine of the class described a chamber in which dust is liberated, and means for extracting the dust therefrom including-a mouth-piece and a box communicating with said mouth-piece, extending substantially the full Width of said chamber and provided With a narrow mouth comn'lunicating With said chamber.

4. A machine of the class described in cluding in combination a. chamber in which dust is liberated, and having a mouth through which the dust. is withdrawn, and a shield R over said mouth for preventing the larger particles from being withdrawn through said month.

In witness whereof I have hereunto signed my name in the presence of tWo subscribing witnesses.

ERNEST PUGTBET.
